Question #289
Shown in the photographs below are the front and the top view of two
colored wooden rods mounted between two plastic plates that cannot be seen
in the pictures because they are just out of view (on the left and right
in the photographs).
The question this week involves what we can say about this geometry,
in particular, whether the two rods might be touching each other at some
point in the picture.
The two rods:
- (a) are definitely touching at some point.
- (b) are definitely not touching at any point.
- (c) may or may not be touching; it is impossible to say.
- (d) a third view is necesssary to solve this problem.
